Winsor & Newton Cotman Watercolour Paints. The Winsor & Newton Cotman Artists' Watercolour Paints are the product of a tradition that dates to 1832 when the company produced the first """"moist watercolors"""" which were made using glycerin. Since then it has been Winsor & Newton's goal to produce the finest watercolors using the largest possible selection of fade-resistant pigments.
